BOILER.,

SPECIFICATION forming part of Letters .Patent No. 701,939, dated Junev10, 1902'. Application filed July 6l 1901. Serial No`..67,2911(Nomodel' l To all whom` t may corr/cern:

Be it known that I, JOSEPH F. ROSE, a citizen of the United States,residing at Danbury,

in the county of Woodbury andState of Iowa, A

(whose post-office address is Danbury, Iowa',) have invented a new anduseful Improvement in Boilers; and I d declare the following to be afull, clear, and exactdescripti'on oftheV manner and produce thegreatest quantity of steam with the least consumption of fuel.

My invention consists in the novel construction, arrangement, andcombination of parts,

as will be specifically pointed out in the claim.

` B the dome of theiboiler.

C designates the smoke-stack, fire-box.

E is the ash-pit. r Y. F is the open space iii-front of boiler proper,connecting the forward iiue withthe returniiues. The small tubeso a aare the'returnflues, running longitudinally through the lower half ofthe boiler,connec tin g the smokestack with the space F in front.

b designates the cylindrical shell of the boiler, the lower po'rtion'ofwhich forms the upper part of covering of the tire-box, and b b thepartitions separating thewater-space of the boiler proper from thewater-space F and the smoke-stack.'

b" designates the boiler-head.

c designates the water-space of the boiler proper, and c the water spaceor chamber beneath the forward iiue.

and D the' d isthe forward Iiue ofthe boilerand consists of a chambersituated directly beneath the ,boiler proper, covering about one-thirdof the lower circumference 'of the boiler-shell andcon-nectingthefire-box with the space F infront. The waterspace c is situatedunderneath thisflue, coveringthesame, and eX- 'tends somewhathigheruponthe sidesof the boiler, as seen in Fig. i2.

e is a lining curved to conform to theshape of the lower part oftheboiler and is situated withinthe rear part of boiler proper. ,Itextendsunder the smokestack,forming a chamber ebetween the tire-boi; andsmoke-stack.

`It projects forward as far as the rire-box and upon the sides of theboiler as high as the openings e' 1I. The space e furnishescommunication between thefwater-space c of the boiler and thewater-spaces c" c" under and.

upon the sides of the fire-box.

fis the door to the fire-box, g the door to ash-pit, and h the door tothe space F in front end of boiler.

As seen in Fig. 4, the lower part of the boileri low chamber of the sameshape of the lower l part of the 'b 'oiler and covering the lowercircumference of the boiler utilizes the heat without detracting fromthe water-space. The water-spaces 0' and c" prevent any waste of heatfrom the forward flue or the fire-box.

Having described my invention',y what I claim as new, and desire tosecure'` by Letters Patent, is-
